o If you select the 1920×1080p resolution, this field will also include an option for a
frame rate of 23.98 (Film):
 Output Resolution: Select the desired output resolution. The values in this drop-down
list are a function of the Video Input Settings, the Input Resolution and the
Frame/Field Rate. Also, please note that some resolutions require additional licensing
for the encoder. If Video Input Settings is set to Manual Selection, the following
resolutions are offered:
o Same as the input (no scaling)
o ¾ scaling from the input
o Low resolutions: 480×270, 320×240, and 320×180, progressive, at half and
quarter frame rates (not available for 1080p inputs)
o HD inputs can be scaled (and re-interlaced if necessary) to SD resolution,
anamorphic (not available for 1080p inputs)
o 720p inputs can be reduced to half frame rate (typically for Internet applications),
as follows:
 1280×720p50 is converted to 1280×720p25
 1280×720p59.94 is converted to 1280×720p29.97
 1280×720p60 is converted to 1280×720p30
o 1080i, 720p and SD inputs can be converted to SD resolution, with progressive
frame rates (ideal for computer displays), as follows:
 1080i59.94, 720p59.94, and 480i59.94 are converted to 720×480p29.97
 1080i60 and 720p60 are converted to 720×480p30
 1080i50 and 720p50 are converted to 720×576p25
The conversions from HD resolutions are done using anamorphic scaling.
o 1080i, 720p and SD

inputs can be scaled to 640×360, with progressive frame
rates, as follows:
 1080i59.94 and 480i59.94 are converted to 640×360p29.97
 720p59.94 is converted to 640×360p59.94
 1080i50 and 576i50 are converted to 640×360p25
 720p50 is converted to 640×360p50

By default, SD signals have a 4:3 aspect ratio, unless they are derived from an HD source with anamorphic scaling.
The 640×360 resolution is intended for 16:9 content. Scaling SD to 640×360 should only be done if the SD signal is
anamorphic to start with, otherwise the resulting encoded signal will have an incorrect aspect ratio.
